0x2207

0x2207 is the hexadecimal representation of the Unicode code point U+2207, which designates the nabla symbol, ∇. In mathematics and physics, this symbol is commonly called the nabla or the del operator and is used to denote vector differential operations.

Encoding and placement: U+2207 belongs to the Mathematical Operators block in Unicode and is widely supported by modern fonts and rendering engines. The UTF-8 encoding for U+2207 is three bytes: E2 88 87. The symbol is typically rendered as a small, inverted delta-like triangle, pointing upward.

Usage in mathematics and physics: The nabla operator acts as a differential operator. For a scalar field f, the gradient ∇f yields a vector of partial derivatives. For a vector field F = (F1, F2, F3), the divergence ∇·F is the scalar sum of the partial derivatives, and the curl ∇×F is another vector describing rotation. The Laplacian is written as ∇²f and represents the sum of second partial derivatives. These operations underpin many formulas in physics, engineering, and applied mathematics.

Typography and context: ∇ is treated as a standard mathematical symbol and appears in equations across disciplines. In some contexts, the symbol is referred to as the del operator rather than nabla, but both names denote the same operator.
